Lamp-pumped rubidium atomic frequency standard (RAFS) is one of the most commonly utilized standards. Over past few decades, RAFS's stability performance has improved rapidly, and best been in 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-13</sup> τ xmlns:xlink="http://www.w3.org/1999/xlink">-1/2</sup> level. In this article, we demonstrate a RAFS with xmlns:xlink="http://www.w3.org/1999/xlink">-14</sup> level for first time. design...
Wuhan Institute of Physics and Mathematics (WIPM) has been developing the space rubidium atomic frequency standard (RAFS) for BeiDou navigation satellite system since late 1990's. Design RAFS aims to realize high stability, small size, long lifetime, reliability environmental adaptability. The physics package was designed in SFT scheme. A slotted tube cavity with size TE011 resonant mode used construct cavity-cell assembly, an argon lamp lifetime as pumping source. microwave chain includes a...
<p indent=0mm>In this paper, we describe the characteristics and performance of space-borne rubidium atomic clocks for BeiDou III navigation satellite system. The frequency stability a clock depends mainly on signal-to-noise ratio (SNR) transition signal, noise interrogating microwave, physics environmental effects To enhance SNR, in design package, use slotted-tube microwave cavity with field-orientation factor higher than 0.9 spectral lamp Xe as starter gas. light emitted from is filtered...
